IMEASURING INSTRUMENT.

To all whom t may concern:

Be it known that I, NORBERT JoHA, a citizen of the United States, residing at Mil-l Y and an object of the invention is to provide a device of this general character having novel and improved means whereby a caliper or the like may be set quickly and accurately to any size in one one-thousands.

Furthermore, the invention has for its object to provide a novel and improved device of this general character which may be employed with convenience and facility as a gage for wire, drills or the like and which may be also employedas a hook scale;

Y The invention consists in the details of construction and in the combination and arrangement of the several parts of my improved measuring instrument whereby certain important advantages are attained and the device is rendered simpler, less expensive and otherwise more convenient and advantageous foruse, all as will be hereinafter more fully set forth.

The novel features of the invention will be carefully defined in the appended claims.

In order that my invention may be the better understood, I will now proceed to de-v scribe the same with reference to the accompanying drawings, wherein- Figure 1 is a view, in plan, of a measuring instrument constructed in accordance with y an embodimentof my invention, calipers beportion is provided with the spaced lugs. 3,

such lugs, as .herein disclosed, being onequarter of an inch in length and spaced one from the other one-quarter of an inch. One

screw, thehead 11 of which is positioned within the enlarged inner kextremity l2 of the slot` 5 and adapted to coact Vwith the shoulders 14 afforded by such enlarged portion l2fwhereby it` will be readily perceived.

that axial rotation of the micrometer screw will result in a longitudinal movement of the shank 6 andthe-head 7 andfin order to determine the extent of movement of the shank 6 and the head 7, I provide the head 12 with thel vernier-15 andthe member 1 with the vernier 16, both operating in a manner which is believedjto be self-evident. The head* 7 projects beyond the opposite longitudinal `edges of the body 1,l thefextended portion 17 being recessed equalgto the spaces between the lugs 3 and coacting with the lugs 3 to afford a means whereby calipers orthe like may be Quickly and conveniently set, as indicated in Fig. 1 of the accompanying drawings-,"rwhile the opposite extremity v18 serves as a hook whereby the device may be employed with convenience and facility as a hook scale. It is to be understood that when the device is employed as a hook scale the head 7 is adjusted tobring the extremity 18 in contact with the adjacentend 'of the body 1. It is to be further observed that the extended portion or extremity 18v projectsV a suflicient extent laterally of the body 1 as to perlmitthe device to be employed as a hook sca e.

By the term hook scale, hereinbefore employed, is intended a measuring instrument provided witha projection adapted to overlie the edge of an article to be measured whereby no particular skill is necessary to position an end of the scale proper flush with the edge ofthe article to be measured.

When it is desired to employ my improvedy l 1 device, as herein disclosed, as a gage for wire, drills or the like, it will be perceived that the inner surface o f the head 7 and the adjacentend of the body 1 are employed in a manner which is believed to be self-evident to those skilled in the art to which my present invention appertains.

F rom the foregoing description, it is thought to be obvious that a measuring in strument constructed in accordance with my V invention is of an extremely simple and comparatively inexpensive nature and 1s parA ticularly well adapted for use by reason of the convenience and facility with which it may be assembled, and it will also be obvious that my invention is susceptible of some change and modification without material departure from the principles and spirit thereof and for this reason l do not wish to be understood as limiting myself to the precise arrangement and formation of the several parts herein shown in carrying out my invention in practice.

l claim:

l. A device of the character described comprising an elongated member provided with equidistantly spaced lugsy along one longitudinal edge, the spaces between the lugs being equal to the length of the lugs, a head slidably mounted upon one extremity of the elongated member, said head being provided in one end with a recess of a length equal to the length of a lug of the member, anddmeans for imparting movement to the hea 2. A device of the characterl described comprising an elongated member provided with equidistantly spaced lugs along one longitudinal edge, the spaces between the lugs being equal to the length of the lugs,a head slidably mounted upon one extremity of the elongated member, said head projecting beyond the opposite longitudinal edges of the elongated member, one end of the head being provided with a recess of a length equal to the length of a lug of the member.

8. A device of 'the character described comprising an elongated member provided with equidistantly spaced lugs along one longitudinal edge, the spaces between the lugs being equal to the length of the lugs, a head slidably mounted upon one extremityv of the elongated member, said head project4 ing beyond the opposite longitudinal edges of the elongated member, one end of the head being provided with a recess of a length equal to the length of a lug of the member, and means for imparting movement to the head, the longitudinal marginal portion of the member opposite to the lugs being provided with a linear scale. j

l. A device of the character described comprising an elongated body provided with an open-ended slot in one extremity, the inner end portion of said slot being enlarged, a head provided with a shank, said shank being adapted to be accommodated within the slot and provided with an axial socket, and a micrometer screw, the head whereof is adapted to be positioned within the enlarged portion of the slot, while the shank of the screw is in threaded engagement with the socket of the shank of the first-named head whereby said head may be adjusted relatively to the adjacent extremity of the elongated body.

ln testimony whereof l hereunto affix my signature in the presence of two Witnesses.
